I know that sounds like a stupid ass question. I have the Logitech wireless mx keys. I wiped the keyboard down so the surface of the keys aren’t sticky, just hard to press down and some have a spasm.
Since a whole ass thing of coffee did not short it, it gives some credibility that it is water resistant. Can I just dump water on it to help it?
Well if you take out the batteries, probably you could - but I think it’s best to just strip it down and I washed mine in the bathroom sink with a bit of detergent (dish soap), then dry it before re-assembling it (I did this with my ancient Logitech K270 keyboard a few times).
The main issue with spills is that they dry sticky, and then the keys will get sticky - so you need to dump out the keys and wash them. On my keyboard, they just pop out and clip straight back in again.
